I've just posted a write-up and video of my latest project, which I'm calling "monomuino." It's a 4x4 button pad communicating with a computer using the monome protocol, and running with the monome software. (Note that this is distinct from my earlier project, which only used the monome form factor; this project is actually acting as if it were a monome, or, rather, one quadrant of the smallest monome.)
